Construcción
Conductores
Solid annealed bare copper 0.4/0.6/0.8mm, as per class 1 of DIN VDE 0295/BS 6360/IEC 60228
Aislamiento
Solid polyethylene 2YI2 type as per DIN VDE 0207-2
Pares trenzados
Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk
Elemento de cableado
Star Quads
Cable Troncal Asamblea
4 Cores are twisted into star quad. 5 star quads are stranded into a basic unit. 5 or 10 basic units each are stranded into one main unit. The star quads are grouped in units and stranded in layers to form the cable core. Standard make up is per DIN VDE 0816 in the Cable Make Up Diagram
Envasado básico
One or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap. These tapes furnish thermal, mechanical as well as high dielectric protection between shielding and individual conductors.
Barrera de humedad
A layer of aluminium tape (0.2mm) coated with PE-copolymer on one or both sides and applied longitudinally with overlap over the cable core to provide electrical shielding coverage and ensures a barrier against water vapor
Vaina
Black low or medium density polyethylene 2YM2 type as per DIN VDE 0207-3, being able to withstand exposure to sunlight, temperature variations, ground chemicals and other environmental contaminants
Ripcord
Ripcord may be provided for slitting the sheath longitudinally to facilitate its removal
Pares de repuesto (optional)
Spare pairs may be provided for large pair cables
Continuidad Wire (optional)
Tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screen
Facultativo Construcción
Jalea rellenos de cable
The cable core interstices are filled with petroleum jelly to avoid longitudinal water penetration within the cable. The water resistant filling compound is applied to the air space between non-hygroscopic tape and shield shield and sheath within the cable core
Cable blindado
Corrugated steel tape armour is applied over an optional inner polyethylene sheath with an overlap. An outer polyethylene sheath is applied over the armour
